With Scarlett Johansson's pregnancy recently announced, it's fair to say fans were a little worried (if only in the back of their minds) that her stake in the Marvel landscape could be lessened for the time being. But rest assured, she's more a part of it than ever before, and a new featurette delving into her Black Widow return in 'Captain America 2' shows she's just as badass.

In 'Captain America 2,' Chris Evans' Steve Rogers/Captain America teams up with Black Widow/Natasha Romanoff to tackle a shadowy threat in Washington, D.C., and, as Samuel L. Jackson says in the latest behind-the-scenes look from ET, their relationship will be tested in an interesting way. Since the events of 'The Avengers,' these two heroes have been working alongside each other on various S.H.I.E.L.D.-assigned missions -- like the "Secure the Ship" moment revealed in the latest extended look -- and the two have such distinct fighting and reasoning styles that their dynamic will be interesting to watch.

Johansson is about to embark on the promotional tour for 'Captain America 2' before the film hits theaters on April 4, after which she'll immediately jump right into filming 'The Avengers 2.' Director Joss Whedon previously said Black Widow takes a larger role in the next Marvel supes team-up, but being that her pregnancy would interfere with the principal filming schedule, Marvel decided to fast-track her scenes.

But before that happens, she and Cap will have to deal with 'The Winter Soldier,' played by Sebastian Stan, whose Bucky Barnes has been genetically enhanced and brainwashed into becoming an assassin. Check out the latest 'Captain America 2' featurette above.
